* x86, numaq: consolidate codeIngo Molnar2009-01-281-122/+0
| | | | | | | Move all the NUMAQ subarch definitions into numaq.c. With this it ceases to depend on build-time subarch features. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: refactor ->cpu_mask_to_apicid*()Ingo Molnar2009-01-281-5/+6
| | | | | | | | | | - spread out the namespace on a per driver basis - clean up the functions - get rid of macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: refactor ->phys_pkg_id()Ingo Molnar2009-01-281-1/+1
| | | | | | | | | | | | Refactor the ->phys_pkg_id() methods: - namespace separation - macro wrapper removal - open-coded calls to the methods in the generic code Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: unify phys_pkg_id()Ingo Molnar2009-01-281-1/+1
| | | | | | | | | | - unify the call signature of 64-bit to that of 32-bit - clean up the types all around - clean up namespace contamination Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: refactor ->enable_apic_mode() subarch methodsIngo Molnar2009-01-281-4/+0
| | | | | | | | | | | Only ES7000 has a real ->enable_apic_mode() method, the other subarchitectures define it but keep it empty. So mark the vector as NULL, extend the generic code to handle NULL -setup_portio_remap() entries and remove all the empty handlers. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: refactor ->check_phys_apicid_present() subarch methodsIngo Molnar2009-01-281-2/+2
| | | | | | | | | - spread out the namespace to per driver methods - extend it to 64-bit as well so that we can use apic->check_phys_apicid_present() unconditionally Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: refactor ->setup_portio_remap() subarch methodsIngo Molnar2009-01-281-13/+0
| | | | | | | | | | | | | | Only NUMAQ has a real ->setup_portio_remap() method, the other subarchitectures define it but keep it empty. So mark the vector as NULL, extend the generic code to handle NULL -setup_portio_remap() entries and remove all the empty handlers. Also move the NUMAQ method from the header file into the apic driver .c file. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: clean up ->apicid_to_cpu_present()Ingo Molnar2009-01-281-1/+1
| | | | | | | | - separate the namespace - remove macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: clean up ->cpu_present_to_apicid()Ingo Molnar2009-01-281-1/+1
| | | | | | | | - separate the namespace - remove macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: clean up ->cpu_to_logical_apicid()Ingo Molnar2009-01-281-1/+2
| | | | | | | | - separate the namespace - remove macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: clean up ->apicid_to_node()Ingo Molnar2009-01-281-2/+2
| | | | | | | | - separate the namespace - remove macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: streamline the ->multi_timer_check() quirkIngo Molnar2009-01-281-1/+1
| | | | | | | | | | | | only NUMAQ uses this quirk: to prevent the timer IRQ from being added on secondary nodes. All other genapic templates can have a NULL ->multi_timer_check() callback. Also, extend the generic code to treat a NULL pointer accordingly. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: clean up ->setup_apic_routing()Ingo Molnar2009-01-281-1/+1
| | | | | | | | | | - separate the namespace - remove macros - remove namespace clash on 64-bit Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: clean up ->ioapic_phys_id_map()Ingo Molnar2009-01-281-1/+1
| | | | | | | | - separate the namespace - remove macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: clean up ->init_apic_ldr()Ingo Molnar2009-01-281-1/+1
| | | | | | | | - separate the namespace - remove macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: remove no_balance_irq and no_ioapic_check flagsIngo Molnar2009-01-281-2/+0
| | | | | | | These flags are completely unused. (the in-kernel IRQ balancer has been removed from the upstream kernel.) Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: clean up check_apicid*() callbacksIngo Molnar2009-01-281-2/+3
| | | | | | | Clean up these methods - to make it clearer which function is used in which case. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: clean up esr_disable() methodsIngo Molnar2009-01-281-1/+0
| | | | | | | | | | | | | | Impact: cleanup Most subarchitectures want to disable the APIC ESR (Error Status Register), because they generally have hardware hacks that wrap standard CPUs into a bigger system and hence the APIC bus is quite non-standard and weirdnesses (lockups) have been seen with ESR reporting. Remove the esr_disable macros and put the desired flag into each subarchitecture's genapic template directly. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: clean up target_cpus methodsIngo Molnar2009-01-281-1/+1
| | | | | | | | | | Impact: cleanup Clean up all the target_cpus() namespace overlap that exists between bigsmp, es7000, mach-default, numaq and summit - by separating the different functions into different names. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: remove NUMAQ_IRQ_DELIVERY_MODE and NUMAQ_IRQ_DEST_MODEIngo Molnar2009-01-281-3/+0
| | | | | | | | Impact: cleanup They were only used in a single place and obscured the apic_numaq template. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: remove IRQ_DEST_MODE / IRQ_DELIVERY_MODEIngo Molnar2009-01-281-2/+2
| | | | | | | | | | | | | Remove the wrapper macros IRQ_DEST_MODE and IRQ_DELIVERY_MODE. The typical 32-bit and the 64-bit build all dereference via the genapic, so it's pointless to hide that indirection via these ugly macros. Furthermore, it also obscures subarchitecture details. So replace it with apic->irq_dest_mode / etc. accesses. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, genapic: rename int_delivery_mode, et. al.Ingo Molnar2009-01-281-2/+2
| | | | | | | | | | | | | | | int_delivery_mode is supposed to mean 'interrupt delivery mode', but it's quite a misnomer as 'int' we usually think of as an integer type ... The standard naming for such attributes is 'irq' - so rename the following fields and macros: int_delivery_mode => irq_delivery_mode INT_DELIVERY_MODE => IRQ_DELIVERY_MODE int_dest_mode => irq_dest_mode INT_DEST_MODE => IRQ_DEST_MODE Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: clean up apic->apic_id_registered() methodsIngo Molnar2009-01-281-1/+1
| | | | | | | | | | | | | | | Impact: cleanup x86 subarchitectures each defined a "apic_id_registered()" method, which could be an inline function depending on which subarch we build for, and which was also the name of a genapic field. Untangle this namespace spaghetti by giving each of the instances a separate name. Also remove wrapper macro obfuscation. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: cleanup some remaining usages of NR_CPUS where s/b nr_cpu_idsMike Travis2009-01-031-2/+2
| | | | | | | | | | | | | | | | | | | | Impact: Reduce future system panics due to cpumask operations using NR_CPUS Insure that code does not look at bits >= nr_cpu_ids as when cpumasks are allocated based on nr_cpu_ids, these extra bits will not be defined. Also some other minor updates: * change in to use cpu accessor function set_cpu_present() instead of directly accessing cpu_present_map w/cpu_clear() [arch/x86/kernel/reboot.c] * use cpumask_of() instead of &cpumask_of_cpu() [arch/x86/kernel/reboot.c] * optimize some cpu_mask_to_apicid_and functions.

* x86: update add-cpu_mask_to_apicid_and to use struct cpumask*Mike Travis2008-12-161-2/+2
| | | | | | | | | | | Impact: use updated APIs Various API updates for x86:add-cpu_mask_to_apicid_and (Note: separate because previous patch has been "backported" to 2.6.27.) Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Mike Travis <travis@sgi.com>
* x86: Add cpu_mask_to_apicid_andMike Travis2008-12-161-0/+6
| | | | | | | | | | | Impact: new API Add a helper function that takes two cpumask's, and's them and then returns the apicid of the result. This removes a need in io_apic.c that uses a temporary cpumask to hold (mask & cfg->domain). Signed-off-by: Mike Travis <travis@sgi.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
* x86 smp: modify send_IPI_mask interface to accept cpumask_t pointersMike Travis2008-12-161-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: cleanup, change parameter passing * Change genapic interfaces to accept cpumask_t pointers where possible. * Modify external callers to use cpumask_t pointers in function calls. * Create new send_IPI_mask_allbutself which is the same as the send_IPI_mask functions but removes smp_processor_id() from list. This removes another common need for a temporary cpumask_t variable. * Functions that used a temp cpumask_t variable for: cpumask_t allbutme = cpu_online_map; cpu_clear(smp_processor_id(), allbutme); if (!cpus_empty(allbutme)) ... become: if (!cpus_equal(cpu_online_map, cpumask_of_cpu(cpu))) ... * Other minor code optimizations (like using cpus_clear instead of CPU_MASK_NONE, etc.) Applies to linux-2.6.tip/master.
